Removed services check and added warnings for simulations
Resolved in Pega Version 8.6.3
Attempting to run an audience simulation resulted in the error "Running simulations is not possible, because the required services are not available. Contact your system administrator to enable the data flow and real-time data grid services". Investigation showed the @DsmServices.pxHasFunctionalNodes("DataFlow","Batch") function call contained in the 'when' rule pyUnavailableDecisionServices was returning false even if all the nodes were in the cluster and all the DSM Services were in NORMAL status. To resolve this, the services check has been disabled and the simulation run will show a warning or fail if a data flow run is queued for more than 30 secs or if there is an issue with querying the underlying metrics storage.

RealTimeProcessingDelay made configurable
Resolved in Pega Version 8.6.3
When using interaction history summaries in Engagement Policy strategies, the check whether a particular action was sent previously was not returning any results for the customers that did have an action "Sent". These records were present in the IH Fact table but the IH Summary tables were missing these records. This has been resolved by making the realTimeProcessingDelay configurable for reading from IH in a real-time flow configurable (done as part of IH pre-aggregation). This may be useful if there can be a difference in time between machines inserting into IH which causes pre-aggregation to miss processing records. The relevant DSS is "interactionHistory/realTimeProcessingDelay", and the default is 5 seconds. This must be set before starting pre-aggregation. This is the difference between the end position and the log time. RuleSet: Pega-DecisionEngine DSS Name: interactionHistory/realTimeProcessingDelay Value: <new delay in seconds>

HandleResponses updated for use with optimized campaign
Resolved in Pega Version 8.6.3
After updating from Pega 8.4, responses were not processed in the pxHandleResponses Data flow if the "pyCampaignOptimization" flag was set to true. This was traced to a missed use case for an optimized campaign, and has been resolved by modifying the condition in HandleResponses.

Updated expression string comparison
Resolved in Pega Version 8.6.3
An expression defined in the proposition filter and/or When rule was evaluated differently depending on whether it was run from within Decision Strategy or run isolated in Expression Builder or a When rule. This has been resolved by updating the string comparison.

Added handling for double quotes on Substrategy shapes
Resolved in Pega Version 8.6.3
After update, there were compilation issues on calling substrategies from strategies using datapage.pxResults as another page. This was traced to the handling for a parameterized data page with double quotes on Substrategy shapes, and has been resolved.
